n is a leather belt attached to the vertical metal support or slide N atthe upper end and to a treadle n at the lower end.

Now, then,when the reservoir M is locked or closed the machine is readyto start. The first thing to be done is to tread on the treadle M, whichpushes the ring or collar N from the metal cylinder N through the tubeor channel N and the inclosed slide N into the reservoir M, and theslide or groove in the reservoir M is sunk enough to allow the inside ofthe metal collar N to be flush with the inside surface of the reservoirM. Then by releasing the treadle the spiral spring around the leatherbelt n forces the vertical slide N back,which also draws the horizontalslide N back, thereby letting the next ring N drop into place ready tobe used on the next bridle, Then take the blank metal with the upturnedflange and put it flange end downward-thus %-in the funnel M. Then byholding the treadle M down until further notice, which pushes the core Minto place in the reservoir ICC M, next push the lever k so that thefly-wheel K is put in motion, which with the aid of the frame L L andpermanent vertical rod L forces the metal teeth L down into thereservoir M, where they catch inside of the upturned flange of the blankjust placed there and force it down into the vertical or narrowest partof the reservoir M, which gives the rounded form to the blank. The coreM is to straighten out any defects in the flange which might arise whilethe blank is being forced into the narrow part of the reservoirlvl. Whenthe metal teethhave gone down to their extreme depth in the reservoir M,they will immediately ascend, and the power must be cut off by the lever10 when the teeth L have gained their greatest distance above the table0. Then release the treadle M and immediately tread on the treadle m,which will open the funnel M and cause the rounded bridle, with the bandN encircling it, to drop out.

P indicates a large power-wheel fastened,

.to the main power-shaft a, which transmits power by'a leather belt totwo pulleys P on e loose and one stationarywfastened to a shaft P, whichis supported by the outside frame or column and a bracket P 10' is aworking arm fastened at the upper end to a Wheel P which is fastened on1 and p is fastened at the lower end to a sliding hammer 19 P representsa slide and lever, which slides the belt to and from the stationary andloose pulleys P 9" represents a narrow pulley fastened to the mainpower-shaft a. r is a similar narrow pulley fastened to shaft r 0" and rare connected by a leather belt, which transmits power to the otherwheel r fastened to the shaft r which is in turn connected by a leatherbelt to two pulleys 1"- one loose and the other one stationaryfastenedto an axle or shaft R.

R is a wheel fastened to the axle or shaft R.

R is a vertical slide.

R is a double arm fastened at one end to the vertical slide R andworking in a groove R at the other end.

R is a Working arm fastened at the upper end to the double arm R and atthe lower end to the wheel R T is a miter co -Wheel secured to a shaft tand T is geared to work with two similar cog-wheels G, fastened on themain powershaft Ct.

T is a small pulley fastened to the shaft T and power is carried fromthe pulley T fastened to a shaft T.

T are two large pulleysone loose and the other stationary-also fastenedto the shaft T.

T is a small auxiliary pulley to be connected by a leather belt with thetwo large pulleys T T is a brace working in the brackets T T is aworking arm fastened at the upper end to the brace T and at the lowerend to a wheel T fastened on the shaft T S is a combination bed andbracket with a stationary hub s fastened permanently at the outer end.

25 is a treadle and lever, which is used to slide the leather belt toand from the loose and stationary pulleys T and at the same time slidesa leather belt to and from the stationary pulley 1". Now, then, to workthis part of the machine all that is to be done is to fasten the rivets,hereinbefore'referred to, in the bridle, which is done in the followingmanner, viz: Taking the bridle, rounded, with collar outside of it tohold it in shape, the first thing to be done is to put one rivet in eachhole made forthe purposeviz.,'two rivets. Then putting the bridle on thehub S, with the rivet-points up, tread on the treadle t, which will movethe brace T upward and the slide R downward at the same time. Thenrelease the treadle as soon as the brace T and the slide R are pressedfirmly against the bridle on the hub S, so that they will act in thenature of a clamp or vise. The grooves shown in the illustration in thebottom of the slide R and in the top of T are to admit of the collarbeing retained on the bridle. Then pressing the lever P 'the hammer-face19 will be worked up and down on the tops of the rivets in the bridle,thereby forming the round heads on the rivets. Then when the heads havebeen formed on the rivets watch when the hammer 19 has reached itsgreatest height from the bridle and immediately take the power from it(19 by drawing the lever P. Then tread on the treadle t, and when theslide R and the brace T are at their greatest distance from s, whichwill be simultaneous,

then release the treadle t',and then the paintbrush bridle hereinbeforereferred to and described in- Letters Patent No. 468,405, dated February9, 1892, will have been completed, with the exception of tempering andnickelplating or otherwise ornamenting the same.

Now comes the main reason for having the collar N". The metal, beingsoft sheet-brass, so as to be worked easily, would require a band tohold the bridle in place after it had assumed its rounded shape, asfrequent handling of the bridle before tempering and during thetempering of the same will require it. After the bridle has gone throughthe four parts of the machine hereinbefore described it is then readyfor tempering, which is done in the usual way, and then the bridle canbe treated to a nickel bath, which is also performed in the usualmanner.

In order to properly mark the patented bridle, a metal marking-stamp canbe attached to the bed-plate E of the machine, so that while the blankis being cut out and the holes punched the patent-mark can be alsoapplied. With the exception of the tables 0' and 0 which are of wood,the entire machine, other than the belts, is of metal.
